Mwille64: Your issue with trying to assign a BBM account to each of your devices listed under one BBID should be a problem encountered by many because often a multiple subscriber does so originally with one email account. Then it becomes necessary to create additional email accounts because certain apps require a unique ID that is tied to an email account. Lots of advice is given how to change passwords but changing BBID's
is not that easy. I'm looking for the same solution.

So far your request appears to have been met with derision with no constructive advice.
It seems posting problems here are a waste of time. Other members/users having the same difficulty are accused of hi-jacking threads.

Simple, ya. The users are not old enough. Go get them an iphone. Where are the moderators? Additonal Gmail accounts? Try that without changing your BBID.
